An ecosystem is made up of species, populations, communities, and a network of communities across a region.A team led by NSF-funded researchers at the University of California-Santa Barbara (UCSB) has...
Beach Replenishment May Have ‘Far Reaching’ Impacts on Ecosystems
Beach Replenishment Far Reaching Ecosystems
2016/4/13
UC San Diego biologists who examined the biological impact of replenishing eroded beaches with offshore sand found that such beach replenishment efforts could have long-term negative impacts on coasta...
Warming Antarctic waters may allow king crabs to "restructure" ecosystems
Warming Antarctic waters king crabs restructure ecosystems
2015/10/13
Rapid warming of the ocean west of the Antarctic Peninsula--the part of the continent that extends north toward South America--makes it possible king crab populations could return from the deep sea to...

If nothing else, research in deep-sea environments teaches us how little we know about such important and productive habitats. The relatively recent discovery of hydrothermal-vent and cold-seep ecosys...
Microbes and the Dissipation of Energy and Respiration: From Cells to Ecosystems
Energy and Respiration From Cells
2015/7/22
In the year 1974, Larry Pomeroy first proposed that microbes were true movers of energy and nutrients in marine food webs (Pomeroy, 1974). This idea was later formalized as the "microbial loop" (Azam ...
In order to measure inputs, cycling, and loss of material in aquatic ecosystems, a wide range of compounds and analytical tools is now available. Biological markers are compounds, or groups of compoun...
A decade of Ridge 2000 and related research has yielded new and refined understanding of events and processes that occur on mid-ocean ridge and back-arc spreading centers, as reported in this special ...
